Today, Snapchat is unveiling the brand new type of Story, which allows you to collaborate on on a single Story with friends, family, and other party guests. The update is arriving on the heels of the app's new creative tools, and it's a smart one. Instead of having friends post individual Stories that you'll watch one at a time, you can all add to one group Story and see an event from multiple angles.

This is Snapchat's second personalized offering: It already allows you to create a custom geofilter, but custom Stories are far more accessible — and, best of all, completely free.

Click through to see how to create, name, and add friends to your own, custom Story. Happy summer of snapping!
